MAC/PHY
Function
mlan0
1
Network interface used for station mode functionality. Can be configured using mlanutl.
uap0
1
Network interface used for access-point functionality. Can be configured using uaputl.
wfd0
1
Network interface used for P2P functionality. Can operate in both group owner (GO) and group client
(GC) modes.
mmlan0
2
Network interface used for station mode functionality. Can be configured using mlanutl.
muap0
2
Network interface used for access-point functionality. Can be configured using uaputl.
mwfd0
2
Network interface used for P2P functionality. Can operate in both group owner (GO) and group client
(GC) modes.
Table 31: Available Wi-Fi network interfaces
☞ JODY-W3 series modules include two radios – 2.4 and 5 GHz – and two MACs for concurrent
dual Wi-Fi use cases, where Wi-Fi interfaces from MAC 1 and 2 operate concurrently in
different bands.
☞ The system/udev managers in modern Linux distributions automatically try to assign
predictable, stable network interface names for all local Ethernet and Wi-Fi interfaces. This
can result in different names being used for the network interfaces. Use the kernel command
line option net.ifnames=0 to override this behavior and use the driver default names.
3.8.4 Assigning MAC addresses
JODY-W3 series has four unique MAC addresses reserved for each module. The first MAC address is
used for Bluetooth and the second and third addresses are used for the two Wi-Fi radio MACs. The
fourth MAC address is reserved for use with other local interfaces.
Example
00:9C:38:00:4B:40 – Bluetooth interface (hci0)
00:9C:38:00:4B:41 – Wi-Fi station interface for radio MAC1 (mlan0)
00:9C:38:00:4B:42 – Wi-Fi station interface for radio MAC2 (mmlan0)
00:9C:38:00:4B:43 – Reserved for use with other interfaces
☞ The Wi-Fi driver automatically assigns locally unique MAC addresses to any additional Wi-Fi
network interfaces, which are derived from the radio’s primary Wi-Fi station interface MAC
address. The use of reserved unique MAC addresses is recommended to avoid possible
collisions with the MAC addresses of other modules.
You can change the MAC addresses of the interfaces by configuring the init_cfg.conf file while
loading the driver. Note that the driver expects the init_cfg.conf file to be present in the directory
relative to /lib/firmware/.
Commented [MZ83]: Update when MAC reservation
has been defined.
Commented [CT84]: This means "… derived from
the primary address of the RADIUS server", right?
Commented [MZ85R84]: No, they are derived from
the primary STA interface of the radio/MAC
